Embodiment approach

[0061] (1) The base station sends pilot information to each user equipment (User Equipment, UE), and each UE estimates the channel gain on each resource block through calculation after receiving it, and feeds back the channel gain to the base station, and the user The information manager sends the channel gain of the UE to the virtual network controller of the operator to which the UE belongs.

[0062] (2) For resource block j, each virtual network controller calculates the utility function increment according to [4] and confirm the quotation The quotation is sent to the resource block manager, and for the operator not belonging to the set A, the resource block manager sets the quotation to 0.

[0063] (3) The resource block manager determines the operator i to be allocated resource block j according to [8] or [10] * , and send an acknowledgment signal to operator i * controller.

[0064] (4) Carrier i * The controller of A determines user k to be allocated resource blo...

Abstract

The invention discloses a network virtualization frame in a long term evolution system and a resource blocks allocation method under the frame. According to the network virtualization frame, a network resource manager is introduced to virtualize a physical base station into a plurality of virtual base stations, and each virtual base station has an independent virtual network controller; network resource management falls into resource block management and user information management, and a resource block manager cannot visit user information; a utility function comprising adjustable parameters is introduced, and the offer and earning of an operator are defined according to the utility function; all the resource blocks are allocated one by one; when each of the resource blocks is allocated, the operator offers, and the operator with the highest offer acquires the resource block, allocates the resource block for a user and considers the speed requirement of the user and the minimum resource block guarantee of the operator in allocation. Through adoption of the network virtualization frame and the resource blocks allocation method, the operator can offer faithfully, the dispatch of interior of the virtual network is customized by the operator which the virtual network belongs to, and virtual networks can be isolated.

Description

technical field [0001] The invention relates to a network virtualization framework in a long term evolution system (Long Term Evolution, LTE) and a resource block allocation problem in the framework, and belongs to the technical field of network virtualization in wireless communication. Background technique [0002] Due to the continuous development of smart terminals and diversified services, the future wireless network presents a development trend of service-oriented and coexistence of multiple wireless technologies. However, due to the close combination of network functions and underlying hardware, traditional networks cannot adapt to the complex and diverse development trends of wireless networks. The emergence of wireless network virtualization technology (Wireless Network Virtualization, WNV) has opened up a new way for realizing the coexistence of multiple networks. [0003] WNV abstracts the network function into a software interface to separate it from the underlyi...
